dear ntozier, sometimes two departments (plumbing and electricians in this case) need to work at the same time on the same issue (same problem, one ticket, 'install a jacuzzi'), and one can finish their job earlier than the other, so they should be able to close that part of the ticket, leaving the other part opened. But, if one department needs to wait till the other finish their job to be notified, job could be terribly delayed. In this case, installing a jacuzzi, it can take one hour for plumbers but 30 minutes to electricians, and of course is too much better to have it installed in one hour than in one hour and a half.Dear Raj, I'll try that, thank you
